Video Source Tracking and Copyright Protection in Video Watermarking

Abstract

Due to extensive usage of internet, the exchange of data between users are also increasing rapidly. Security and copyright protection are becoming important issues in digital media applications and services. Owners of the digital products are troubled about illegal copying of their products. Digital watermarking throughout the last decade is improved due to the increase in the need for copyright protection. More specifically Creative Commons License (CCL) has been established as a expedient method to protect copyrights of user generated digital products .However, the lack of technical method to protect CCL causes illegal manipulations and sharing of CCL. This paper presents, embedding dual watermarking system which embeds both robust watermarks and semi-fragile watermarks for CCL protection and manipulation detection. A robust watermark is generated, in order to withstand frame drop and rescaling, which increases the overall robustness. Then the fragile watermark is embedded at DWT domain, robust watermarks are embedded at spatial domain.
